PIN AND JOINT.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed December 26, 1908. Serial No. 469,497.

To all whom it may concern:

Be it known that I, ELIsHA A. PHINNEY, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins and Joints, of which the following is a specification.

My invention relates to improvements in pins and pin joints and the object of my invention is to provide a pin having a pivot and a stop integral with the pin itself, in

combination with a joint provided with suit able lugs for the engagement of said stop so as to limit the movement of said pin in both directions. I accomplish these objects in the manner shown in the accompanying drawings in which the various parts are indicated by the same letters throughout.

Figure 1 constitutes an elevation of the brooch showing my pin and joint; Fig. 2 a side view of the pin; Fig. 8 a top view of the same; Fig. 4 a sectional view of the pin showing the pivot and stop on the line mw of Fig. 2; Figs. 5 and 6 are respectively end and side views of my joint; and Fig. 7 a vertical section of the brooch, pin and joint on the line g q of Fig. 1.

In Fig. 1, c is the body of the brooch, a the pin, d the catch, Z) the pin joint or bearing and a the stop which is integral with the pin itself.

In Fig. 2, a represents the pivot, and a the flattened head of the pin carrying the pivot a and the stop a A vertical view of these parts is given in Fig. 3 and a sectional view in Fig. 4.

In Fig. 5, 6 represents the base or body of the joint or bearing having the side or check pieces b--?) projecting therefrom in the usual form, and which side pieces have integral therewith the lugs b b these lugs are best seen in Fig. 6, which also shows the perforation b for the insertion of the pivot a of the pin a.

The pivot a and stop a are struck by the dies in the same operation that flattens the head a of the pin a, both the stop and pivot being integral and of the same piece with the flattened head itself, and project in one direction but in both directions by the stop a of the pin engaging the projecting lugs 79 b of the joint or pin hearing 6-4). The lugs b on one side of the bearing are in the same plane as those at the opposite side, and as lugs are provided on opposite sides of each cheek-piece, the stop a engages with two lugs in each extreme position of the pin.

The joint is attached to the brooch by soldering or any other suitable method. I am aware that prior to my invention pins have been made having pivots integral with the pin itself. I am also aware that a pin having a stop integral with such pin 'ing its shank flattened at one end to con stitute ahead, said head comprising a flaring portion terminating in a circular portion, the said flaring portion terminating in the shank, a pair of lateral lugs formed integral with said circular portion centrally thereof, said lugs extending in opposite directions with respect to each other and furthermore extending in the same plane and constituting a pivot, a pair of lugs formed integral with said flaring portion in proximity to said circular portion, extending in opposite directions with respect to each other and further extending in the same plane and constituting a pair of stops, a bearing embodying a pair of spaced apertured cheek-pieces in which the lugs constituting the pivot are mounted, each of said cheek-pieces provided with laterally projecting lugs, the adjacent lugs on the cheek pieces extending in the same plane with respect to each other and further extending at right angles with respect to a stop and the pivot, said stops adapted to engage the lugs of the cheek-pieces for limiting the pivoting movement of the pin in 10 either direction.

In testimony whereof I ailix my signature in presence of two witnesses.
